Yes, 0.13.0 is finally here. The feature list is sizeable, so you can find the full list of changes in the ChangeLog, but the main thing is the huge change to the material structure, which lets you not only use both high-level and low-level vertex and fragment programs (shaders), but gives you a robust framework to use them in, which includes major enhancements to the material scripting system, intelligent fallback techniques for older cards, material level of detail changes, pass iteration, automatically controlled parameters and lots more. Beyond that, there are other notable features such as compressed texture support and volume texture support. But anyway, full details are in the changelog 🙂
